AI bot checker: can ChatGPT, Claude and Gemini read your site?
The checker reads your robots.txt the way each named AI crawler would, looks for llms.txt, and counts how much text machines can read without running JavaScript.
Two kinds of AI bots, two different decisions
Bots that put your site into answers
Googlebot (including AI Overviews), Bingbot, OAI-SearchBot, ChatGPT-User, Claude-SearchBot, Claude-User, PerplexityBot. Blocking these removes your site from the places people are asking.
Bots that collect training data
GPTBot, ClaudeBot, Google-Extended, Applebot-Extended, CCBot, Meta-ExternalAgent. Allowing or blocking them is a business choice; blocking this group does not drop you from Google Search.
